My coffeescript is as following:
level = switch
when 0 <= value <= 1 then 0
when 1 < value <= 2 then 1
when 2 < value <= 3 then 2
when 3 < value <= 4 then 3
when 4 < value <= 5 then 4
else 6
Why do I get :
Uncaught Error: ExecJS::ProgramError: [stdin]:15:4: error: unexpected when when 1 < value <= 2 then 1
This works fine:
when value <= cool then 0
when value >= warm then 4
else
bucketSize = (warm - cool) / 3 # Total # of colours in middle
Math.ceil (value - cool) / bucketSize
This also works:
level = switch
when value <= 1 then 0
when value <= 4 then 4
else 5
untill I add when value <=2 then 1
It was all about indentation.
level = switch
when 0 <= value < 1 then 0
when 1 <= value < 2 then 1
when 2 <= value < 3 then 2
when 3 <= value < 4 then 3
when 4 <= value <= 5 then 4
else 5
I kept the code here : http://www.coffeelint.org/
and then checked the indentation.
